4D printing is the next development to 3D printing where the fourth dimension is time. This emerging technology will allow us to print objects that then reshape themselves or self-assemble over time. Think: a printed cube that folds before your eyes, or a printed pipe able to sense the need to expand or contract.

Nanotechnology and bioengineering are technologies that will contribute greatly to create a world free of work and money. Everything, absolutely everything can be built from a seed containing all the instructions for its self-assembly, which is true for every living thing since they all come from a single cell or a seed. Everything we need could be made of living materials and grow from a seed. A house, a bicycle or a mobile phone will self-assemble just as trees, plants or animals. Everything will be fully integrated in the recycle process of nature so as to produce no pollution and no waste during and after usage.Even if our resources are limited, we can satisfy our limitless needs thanks to an endless recycling of those resources.

4D printing is one of the technologies which paradism will develop and prioritise.
